.'l'o all @atom/ef may concerm Be it known that I, GEORGE C. Sinfonie, acitizen of the United States, residing at New York city, in the countyof New York,

State of New York, have invented certain 'new and useful lmprovements inHollow Wareg' and l do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same. i

he present invention relates to hollow articles such as barrels, kegs,cartons, tubs and the like. While the articles may l'ind their widestfield of use as containers :tor all purposes, the invention is notlimited to articles of this nature a barrel hav-ing an but is intendedto include tubular structures adapted for a wide variety of usesespecially in the manufacture of furniture and similar articles. f

ll-leretofore, containers have been made of paper.4 or container-board.formed in the shape of drums and sometimes reinforced by hoops.4Containers of this general type with slight modifications have I.goneinto extensive use in sizes ranging from small mail! ing tubes uptoreceptacles havingr a capacity of several gallons, but vso far as l amaware it has never been possible to give to any of these'containers thecorrect shape of l arch or bilg'e midway between the ends. It is almostessential in the case'of barrels designed to carry heavy loads that theybe formed in this shape in order toi obtain the strength of the archedor bilged portion as well as to permit of their being easily turned upon end ror conveniently directed in their course when t rolled along. lthas also been to make tapered pails, tubs and similar articles outofpaper or like materials excepty a process of molding pulp when in asoftened condition andthereafter allowingit toharden and by treatinglrit with impervious substances to render the articles water-prooi', or bycutting` out a paper blank Aadapted to form a tapered pail shell whenthe extremities oi the blank are brought todgrether and fastened by'rivets or otherwise.

yhe latter construction involves a seam running parallel to the axis ofthe pail and this is objectionable as the seam may open impossible whenthe pail is-used.

lt is an object of the present invention pails,.

to produce hollow articles composed of a strip or 'strips of suitablematerial wound in a series of overlapping convolutions which are unitedto each other to form in effect a substantially integral structure. Thearticles may then be treated with any suitable substance to render themimpervious to the action ,of any liquids or other materials which, itisintended they shall contain.

he articles may be formed at a minimum cost. and a wide variety ofsubstances may be used for their formation as, `for instance, metallicstrips and mineral fibers such as asbestos, or cheaper kinds of materialsuch as the common .forms of vegetable tiber, such as the pulp of wood,straw, or any other appropriate substance, the only requirement beingthat the material must be capable of being' `formed into ribbons orwebs, and preferably the material, if paper, should be practically freefrom sizings, fillers and the finishing substances generally found incommercial papers.

rlhe articles of the present invention may be constructed of materialwhich has been previously coated with a suitable, sclidied or driedadhesive which is moistened just prior to the operation of forming thearticle, y means of this method the strips of mai terial maybe woundrapidly and hence the finished article may be produced in con-vsiderably/'less time than is required to make similar articles by themethods at present in common use. i

ln the case oi' many containers, and particularly barrels, the heads areapplied after the body of the barrel has been formed and the presentinvention meets this manufacuring practice by forming articles withcomparatively thick chimes into which the heads may be driven andretained in place y glue or in any other manner. l

meng the many eluded vention, a few typical ones are illustrated in theaccompanying drawings in which Figure l shows an exterior view of abarrel;

kinds of articles in lllO within. the scope oi' the presentin l Fig. 2is a View in longitudinal cross section and Fig. l is a View in crosssection of a portion of the cnil oi" an article showing the relation ofthe successive windings.

it is inencled that. the articles shown herein shall be produced upon amachine like that shown in my cci-pending application5 Serial Number132166. iierl July 33. i917, anal in accordance with the processescovered in my co-pencling application, Serial will be unlers-ioocl,however, that the articles may formed on machines other than of', theparticular form disclosed in these applications proviflecl such machinesare adapted io give the articles the required structural features.

These structural features are, in the case o Lche barrel shown in Fig.2, (he provision of a number of super-impose@` convolutions or innercylindrical bands making up the chimes oi 'olie barrel as indicated at10.. These two chimes are made by partially sliiing a band of materialinto t 'o strips and then Winding; the sl'rips upon suitable mandreis asdescribed at length in the applications referred "ro above. Theinterniecliae portions il of ihe barrel comprise oppositcly direc-.reelelonhated spirals each formed. by a series of nvolutions each of whichis slighly displaced with respect to the preceding one bu*u pa 'tiallyoverlaps the same, so illicit the flianielter oi the barrel increasesgradually toward the central or bilp'jge portion in crier to give thisportion of Jche barrel additional strength, a

number of conyolutions o' material are wounfl about he central porion,and. the

material while is being wouncl al1 this slage of the operation is notslil', as it is when forming; the chimes and he incerniecliaie portions.The i'inisiieil article appears on the outside as own in Fig. l and maybe pained or otherwise corererl as desired. if ii is intended to be usedfor holding; liquids which may penetrale the material of Wnich it isformed. it may be coated on the inside wih suiable material lo render itimpervious to these liquiris. llrlhen the arbicle is iorinecl of szripsof material which have been previously eoaerl with adhesive and aremoistenefl just prior to the formation of the article7 theconi/'olutfions thereof be come firmly united to cach other when 'theadhesive has hardened and` the resull'. is srueture which possessesmaximum strength, but is of comparatively hgh/i. weign..
